'vALvii specification of Letters Patent. i Patented Feb. 27, `191Application filed January 31, 1813. Serial No. 745,420.

To all'. whom t may concern.'-

Be it known that I, PHILIP EoiI'ENRoTi-i, a citizen ofthe United States,Vresiding inf Philadelphia, Pennsylvania, have invented certainImprovements in. Valves, of which the following is a specification.

The object ofv my invention is to provide al valve with means designedto prevent the iary seats, which member'is passed overaV cutting of theseat by the Wire-drawing of steam or liquid under high pressures; r

My present invention While comprising fthe provision of auxiliary seatsadjacent the Y vthrough the same. These latter main seat, over which thesteam or liquid underr pressure must pass before it passes the mainseat, includes certain improvements in said auxiliary seats. In thepresent construction, space is provided between the auxiliary seats andthe lmain seatV for A the expansion of the-initial body'of steam orliquid leaking by said auxiliary seats so that in passing the main seat,it Will be in sufficient volume to avoid cutting of the latter, and myinvention alsoV includes certain improved details'of improvement overlSerial No. 745,419. ment is designed to provide a structure in which theauxiliary seats are relieved .to a certain extent of the danger of Wearand Vcutting by the Wire-drawing of the. steam.

These and other features of my invention are more fully describedhereinafter, refer'- ence being had to the accompanyingdraw'- ings, vinWhich:VV Y i Figure V1, is aY sectional elevation of a valve having andcontaining the improvements forming the subject of my invention,

and Figs. 2 and- 3,'are detached views, of'

the valve and its seat, showing modified constructions .Within the scopej of my Vinvention.

it Will be understood that itsY use isV not limited to employment withsuch structures, and with modifications obviousV to anyl one skilledinthe art, my improvements may be applied to valves of` any description.

In the structure shown in Fig. l, l represents the shell or casing ofthevvalve hav-V ing the Vusual diaphragm or division-Wall la which, in thepresent instance, is provalve.

i'Vhile'niy present invention has been ap-Y. pliedyto what is 'known asa globe valve,

yvided with aremovable seat 2, engaged vby a packing disk or ring 3 of avalve ,body

I4f.,.carried by ast'em Y5; saidstem beingrre- .tained in place by a.threaded Vcollar G of usual formengagingV a head-7v onjlthe end ofsaid'stem. In the 'present instance, the packing disk or ring 3 is heldin place by; a member' 8, which forms onejof' the auxilthreaded stem9,.and retained by a nut v10 carried thereby; said nut being heldagainst movement by a Cotter pin v1l extendingr parts may be of theusual construction. v

In the present construction, I recess thel inner ivall of the seat .2,and provideV the same 'with a ring 12er' suitable material, Which maybemetal or any suitable composition available yfor the purpose, havingy lal.truly annular Wall, with which engages the depending annular Wall l?)of themem-` 'ber 8 the latter beingofv the Isame material asAtheringlQ.v Theiannular- Wall 13 is per-A forated at ll, and steamgoryotherliquidVY to Y. vided with an annular ivall'll with a rounded upperedge forming the seat,proper,inV

dicated at 2, and from Va .point belou7 `said ivardly, as clearlyindicated, substantially a companion case led January 31, Y'19113, ,passthe main seat-must pass through these My present arrange Yupper Vedgethe-bodyf'of the seat slopes Yin-V parallel toy the Vtaper `or bevel` ofth'emem- -ber 8, securingthe packing vring Sito Athe The upper edgeyofithe ringv-l2l alsoV follows this bevel.` By thi'smeans, a space. l5is pro-vided in Ywhich anysteam or other fluid leaking past theauxiliary seat formedk by the' ring 12 and thesleeve Wall' 13 .may

'enter and expand sothat ,whenthe packing' ringof the valverisraisedfioni said seat 2 the steam, Yinstead 'of-ivirefdrawing' andcutting` said seat, 'will not passthe saine.

-inany appreciablequantity until the val-ve. Lis lifted ventirely kclearof said seat. *P1-actically all of the'steam or liquid passing theauxiliary seats will go through the perforatio'ns so that the contactingsurfaces of ring 12 and Wall V13 Will not suier by thevviredrawing ofthe passing bodies of fluid. In addition, the wall 13 is grooved at 16so that the pressure of steam, or other liquid passing through theperforations 1a will tend to equalize.

In the structure shown in Fig. 2, the valve body is provided with adepending portion la which may be integral therewith and is grooved at16rl and lies adjacent a wall 19 below the main seat 2, which wall isalsoV grooved at 20. The depending portion la of the valve is perforatedat 14a. Any steam or liquid trapped by the grooves will be graduallyadmitted to the space between the valve and as the valve is lifted,while the main volume passes through the perforations.

The structure shown in Fig. 3, is substantially the same as that shownin Fig. 1, excepting that the wall 19a of the main seat 2 is grooved at20a; the ring 12 being omitted, while the depending portion 13a of themember S is also grooved atV 161J in addition to its perforations 14d.

It will be seen from this construction that the auxiliary seats whilesubject to possible wear, can be readily renewed and that the main seatof the valve is absolutely prevented from cutting or damage due towiredrawing of the steam or any liquid under pressure. In addition, therenewable auxiliary seats are partially protected by the passage of thesteam through the perforated walls.

rllhis design of valve is best suited for high pressures, requiring moremovement of disk away from seat for a given pressure; pressure beinggradually built up, and areas of opening increased by bringing suitablyarranged openings past top of seat ring 12,

, and at the'same time removing valve disk 3 away from valve seat 2,preventing cutting of their surfaces. Also for throttling supply ofsteam; the cutting of material taking place at upper edge of ring 12 andopenings, as shown, in place of face of seat 2 and disk 3 as in ordinaryglobe valve construction, which mean their rapid destruction.

The object of this design of globe valve is to practically' stop allflow of steam or fluid through same during the operation of opening andclosing of valve; therefore eleminating all cutting of valve seat andvalve disks.

I claim:

1. The combination, in a valve structure, of a main valve, a seattherefor, a removable auxiliary seat carried by the main seat anddisposed below the latter and constituting one engaging surface, and adetachable perforated sleeve for engagement with said auxiliary seat andconstituting a second engaging` surface, one of said surfaces beingprovided with annular grooves.

2. The combination, in a valve structure, of a main valve, a seattherefor, packing carried by said main valve, a removable auxiliary seatcarried by the main seat and disposed below the latter and constitutingone engaging surface, a detachable perforated sleeve for engagement withsaid auxiliary seat and constituting a second engaging surface, one ofsaid surfaces being provided with annular grooves, said detachablesleeve engaging the packing ring of the main valve, and means forsecuring said sleeve in place.

3. The' combination, in a valve structure, of a main valve, a packingring carried thereby', a seat therefor, an auxiliary seat, and aperforated sleeve for peripheral engagement therewith carried by themain valve, said perforated sleeve having annular grooves adjacent thesurface of said auxiliary seat. Y

4e. The combination, in a valve structure, of a main valve, a packingring carried thereby, a seat therefor', a removable' auxiliary seatbelow the main seat, and a renewable perforated sleeve for peripheralengagement therewith carried by and movable with the main valve, saidperforated sleeve having annular grooves adjacent the surface of saidauxiliary seat.

5. The combination, in a valve structure, of a main valve, a packingring carried thereby, a seat therefor, an auxiliary seat disposed belowthe main seat, and an auxiliary valve for peripheral engagementtherewith carried by the main valve, one of said auxiliary membershaving annular grooves in its active meeting face.

6. The combination, in a valve structure, of a main valve, a seattherefor, a separable auxiliary seat carried by the main seat below thelatter, a detachable member having a depending wall forming anothervalve for engagement with said auxiliary seat, one of said latterelements being peripherally grooved, and means for securing saiddepending Wall member to the main valve.

7 The combination, in a valve structure, of a main valve, a seattherefor, a removable auxiliary seat carried by the main seat, and aremovable member for engagement with said auxiliary seat, one of saidlatter elements being annularly grooved.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
